which the following is a full, clear, and exact description.

Our invention relates to improvements ingas-making apparatus.

The improvement consists in constructing the apparatus in such manner asto allow of its being divided into two distinct parts, which may eitherbe worked independently or to gether.

The invention will be described with reference to the accompanyingdrawings, in which-- Figure 1 shows at Aa front elevation, at Bavertical cross-section, at O a similar section taken through theregenerators, and at D a rear elevation of the apparatus. Fig. 2 representsa series of horizontal sections taken, respectively, at E throughthe lower part of the furnace and regenerators, atF through the saidfurnace and regenerators at about midheight, at G through theair-passage to the regenerators, the (listributing-chamber, and upperpart of the furnace, and at H through the oblique line 1 2, Fig. 3,passing through the combustion-chamber, the outlet-orifices for thegases, and the point of contact of the latter with the air. Versevertical sections taken through the f urnace, the grate being arrangedon the left and right hand sides, respectively. Fig. 5 is a transversevertical section taken through one of the rows of retorts and thecorresponding regenerator. Fig. 6 is a transverse vertical section takenon line 3 4, Fig. 1, showing the combustion chamber and airdistribution. Fig. 7 is a vertical section taken on line 5 6, Fig. 4,showing the circulation of the gases {)oward thecombustion anddistributing cham ers.

The same letters of reference represent the same parts in all thefigures.

a is the furnace, so arranged as to divide Figs. 3 and at are trans;

the apparatus into two distinct parts, which may be heated eithertogether or separately. To this end I may provide the exitpassages forthe products of combustion leading from eachregenerator into the commondraft-passage M with separate dampers or their equivalents N, wherebythe draft of the products of combustion through either regenerator andaround either set of retorts can be cut off, thereby compelling all ofthe products of combustion to pass around the air-tubes of, the otherregenerator, and consequently restricting the heating action to theretorts above said latter regenerator.

b are the retorts disposed on each side of the furnace at, the numberand arrangement of which may be varied. The arrangement of the furnaceitself may also be varied.

c is a mouth or chute, of cast-iron or earthenware, having a bend, asshown, whereby the charge of coke may be introduced into the furnace a.

It will be noted that in heating the retorts the furnace-gases risethrough an uptake e and thence pass into the distributing-chamber f.Said distributing-chamber is divided into separate compartments by thepartition-wall 9, so that either or both of the sets of retorts may besupplied, according as the draft is es- 'tab1ished,'through a single oneof the regenerators or through both. The partition-wall serves to cutoff-direct communication between the two sets of retorts and thecombustion-tines, within which the sets of retorts are respectivelylocated, so as to insure the working of the two parts of the bencheither independently or together. The distributingchamber discharges itsproducer-gas through openings 1 above the retorts and meets thereat asupply of air issuing from the air-supply flues a, which are incommunication with the air-passages of the air-regenerators, as shown.The products of combustion flow downwardly past the retorts,said'retorts being alternately connected along one edge to the one sideor the other of the combustion-fl ues, so as to compel the products ofcombustion to pursue a zigzag path around and about the retorts. Afterpassing the retorts the waste gases pass through the heating-dues of theair-regenerwardly-directed flames.

' or rear, as shown, respectively, in Figs. 3 and 4. As the chute 0extends upward and its mouth opens out to the same level or platform asthe mouths e of the retorts, the furnace can in this mannerbe chargedfrom the same level as the retorts, which greatly facilitates working.

This improvement is applicable to all kinds of gas-making apparatus.

As will be seen from the drawings, and more especially by the arrows inFig. 5, this system also admits of heating the retorts by downlVeutilize the space left beneath the retorts by reason of their inclinedposition for containing the regenerators d.

By combining the several parts of the apparatus as described we areenabled to construct it in a more economical manner, as well as tofacilitate the charging and insure a more efficient action.

We claim- 1. A gas-retort bench having a centrallydisposed furnaceprovidedwith an inclined vault or arch and two sets of inclined retortson opposite sides of said furnace in passages between the side walls ofthe furnace and the adjacent side walls of the bench, substantially asdescribed.

2. A gas-retort bench having avaulted furnace, retorts located at theside of the furnace, an uptake at the rear end of the vaulted furnace, adistributing-chamber located above the furnace-vault and connected withthe uptake and having discharge-openings above the retorts, andair-supply fines also opening above the retorts, substantially asdescribed.

3. A gas-retort bench having inclined retorts whose charging-mouths arearranged at substantially the same level above the bench and having thefurnace thereof provided with a charging-chute whose mouth is atsubstantially the same level with the charging-mouths of the retorts,whereby the furnace can be charged at the same level as the retorts,substantially as described.

4:. A gas-retort bench having a centrallydisposed furnace, inclinedretorts at each side thereof, and a regenerator in the rear of each ofthe substantially triangular spaces comprised between the lower retortsand the back wall and base of the bench, substantially as described.

5. A gas-retort bench having a centrallydisposed furnace provided withan inclined vault or arch, inclined retorts at each side thereof, and aregenerator in the rear of each of the substantially triangular spacescomprised between the lower restorts and the back wall and base of thebench, substantially as described.
